Imagine that some respectable country would go far beyond legalizing cryptocurrency and start one of its own. It would surely be no scam and it would probably have a strong support, but would there be any drawbacks to the currency and the state itself? Would it get more attention than some of the biggest coins now?
Governments of different countries have already begun to create their centralized crypto currency, and even more express their intention to create it. I think that this will be a good addition to the national paper money. National centralized crypto currency will help raise confidence in decentralized types of crypto currency, as the population will see a serious attitude of state bodies to the crypto currency and will be convinced that this is not fraud and that the state itself recognizes it. The centralized crypto currency of its state can be useful to its citizens, at least at the initial stage. And what will happen next - we'll see. It is unlikely that such a crypto currency will be of interest to citizens of other countries.
